Question 6 1pt 0 1 You wish to test the following claim (Ha) at a significance level of o = 0.001. For the context of this problem, Ad = /2 - /1 where the first data set represents a pre-test and the second data set represents a post-test. Ho: Hd = 0 Ha: Ha # 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = 4 subjects. The average difference (post - pre) is d = 23.8 with a standard deviation of the differences of Sd = 11.6. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) or O greater than o This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test from pre-test is not equal to 0. O There is not sufficient evidence to warrant rejection of the claim that the mean difference of post- test from pre-test is not equal to 0. The sample data support the claim that the mean difference of post-test from pre-test is not equal0 Question 9 B 1 pt '0 1 Test the claim that the proportion of children from the low income group that drew the nickel too large is greater than the proportion of the high income group that drew the nickel too large. Test at the 0.1 significance level. 24 of 40 children in the low income group drew the nickel too large, and I" of 35 did in the high income group. a] If we use L to denote the low income group and H to denote the high income group, identify the correct alternative hypothesis. 0311px. aa OH1:#L 3> Mi 031331. :z'PI-I 0311131. >PH OHliL
